Mueller’s Russia probe, by the numbers

New court filings due this week could offer fresh insight into the information President Donald Trump’s former confidants shared with special counsel Robert Mueller’s team and where the probe is headed now.

The filings will come as Mueller’s team reportedly moves into the final stages of the investigation into Russian meddling in the 2016 presidential election and possible ties to the Trump campaign. According to a Yahoo News report, Mueller’s prosecutors told defense lawyers representing witnesses in the probe that they were “tying up loose ends.”

As Mueller’s far-reaching probe continues to unfold, we took a by-the-numbers look at where it stands.

18 months (or 567 days): the amount of time that has elapsed since Mueller took on the job. Deputy Attorney General Rod Rosenstein appointed Mueller, a former FBI director, to oversee the investigation on May 17, 2017. Right now, the probe is shorter than all other special investigations in modern history, such as the Iran-Contra, Watergate and Whitewater investigations, which extended into at least 4 years.

Five: the number of Trump’s former business and campaign staffers who have pleaded guilty in the probe and agreed to cooperation deals:

Michael Cohen, former vice president of the Trump Organization and Trump’s former personal attorney. Cohen pleaded guilty to lying to Congress last week. He also pleaded guilty to tax fraud and campaign finance charges in a separate court case.

Michael Flynn, former national security adviser. Flynn pleaded guilty to lying to the FBI.

Paul Manafort, former Trump campaign chairman. Manafort pleaded guilty to financial and tax crimes as well as to foreign lobbying charges. Last week, prosecutors alleged Manafort violated the terms of his cooperation deal by lying to investigators.

George Papadopoulos, former campaign adviser. Papadopoulos pleaded guilty to lying to the FBI.

14: the number of attorneys known to be part of the special counsel team. Mueller assembled the team of prosecutors from the Justice Department as well as from a law firm where he previously worked.

Nearly $17 million: the known cost of the investigation (so far). The Justice Department reported that it spent $16.7 million on staff salaries, equipment, travel, rent and other expenses through March 31, 2018. DOJ has not released an updated number that includes the costs incurred during the last eight months. Trump has repeatedly claimed, without evidence, that the investigation has cost much more. Last week, he tweeted that it has cost $40 million.
